BRAKE-LEVER.

EPISCIFJICATIGN forming part of Letters Patent No. 328,971, dated October 27, 1885. Application filed February 2G, 1885. Serial No. 157,261. (No model.)

T0 all whom, t may concern:

Be it known that we,WILLIAM HENRY HAR- RisoN POWELL and JOHN TnoMAs GRIMM, of l/Vest Finley, in the county of l\/Vashing ton and State of Pennsylvania, have invented an Improved Brake Lever for WTagons, of which the following is a specification.

The special object of the invention is to connect the lever with the rack by locking mechanism which shall be at thesame time perfectly secure and yet more convenient and reliable than such as are now in public use, also, that may be operated by the hand or foot and on or oft' the wagon, also, that it may be attachahle to either sidel or to the rear of wagonbody.

Figure 1 of the drawings is a side elevation showing all the parts in their proper local relation and ready for use. Fig. 2 is a sectional elevation of the locking mechanism, so as to make clear to the eye how the device is locked or unlocked. Fig. 3 is a detail view of the pawl or detent and pull-bar, the latter being for the purpose of unlocking the detent.

In the drawings, A represents the lever for moving the lock mechanism from one point to another on the rack-bar B, which passes through the slot a. In this slot is also placed the pivot C, on which is fnlcrnined a lever, D, which carries at each end the side pivots, d d. On these side pivots are made to turn the bifnrcated ends of pull-rod E and the forked detent F.

G is a keeper attached to lever A in such a position that the detent can slide back and forward under it and upon the face of lever.

H is a forked lever treadle pivotcd to and straddling lever A, so as to work against the collar e on the pull-rod E. By .this means the pull-rod is forced against the resistance of a surrounding spring, I, which bears against the side ring, a2, on lever A. rlihus the detent F is unlocked from the rackbar, so that the brake may be taken off and the lever moved back. The pull-bar Ehas also an end ring, by which it may be handled.

ai represents the hole in which is secured the connection that operates the brake mechanism, which may be of any suitable kind, and is no part of my invention.

The rack-bar B is preferably secured to a wagon-side by the screw-clamps?) b b2, and has the intermediate spacerblocks, J J. through which pass the long screw-bolts of the clamps b b, one end of said bar being bent down and held directly to the wagonside, as shown in the drawings.

Ii is a bracket in T form, and secured to w agon-body by the screw-clamps k k, one near the end of each arm, and has pivot k.

Having thus described all that is necessary to a full understanding of our invention, what we consider tobe new, and'dcsire to protect by Letters Patent, is

l. In wagonebrake levers, the transverse lever D, pivoted at C to thc lever A, in cornbination with a pivotcd pull-rod, E, at one end, and at the other with a pivoted lockingslide, F, as shown and described.

2. In wagon-brake levers, the locking-slide F, slotted to straddle rack B, and working in a keeper, G, on lever A, as shown and described.

3. The combination, with lever A and rack B, of the pivot O, lever D, spring-actuated rod E, slotted slide F, and keeper G, all arranged as shown and described.
